The mechanism of the drawing machine in this pavilion is similar to that in Solar-drawing observatory (Large spheres). Here, however, three different sizes of spheres are positioned in a circular plate that is suspended above the turning paper. The position and sizes of the spheres correspond to certain days of the year and hours of the day, so that the resulting drawings will be different for each day of the year. Here, too, the drawings will be first displayed within the pavilion and then in the gallery at the National Museum of Qatar.
